If you use the supplied system control cable to connect a subwoofer to a Yamaha component
(e.g., Yamaha Digital Sound Projector that features a system connector jack), turning on or off
the power to the connected component automatically turns the subwoofer on or off.

Connection example
How the System Connection works
Notes
• For this feature to be available, the POWER switch on the subwoofer must be set to ON.
• Powering on/off via the system connection takes priority over the Automatic power-switching
function. (While the unit is turned on, the Automatic power-switching function is enabled.)
• To modify the settings of the connected components, please refer to the owner’s manual that
came with the respective component.
After all connections are completed, plug the subwoofer
and other audio/video components into AC outlets.
This function automatically places the subwoofer in standby mode if the subwoofer does
not detect a signal from the amplifier for a certain period of time. The subwoofer
automatically turns on as soon as it detects a signal from the amplifier.
The Automatic power-switching function works as follows when the AUTO STANDBY
(HIGH/LOW/OFF) switch is set to LOW or HIGH. (Normally, set the switch to LOW.)
How the Automatic power-switching function works
*1
When the Automatic power-switching function is enabled, the subwoofer will detect a bass signal input of
below 200Hz (such as sound effects of explosion in action movies, bass guitar or bass drum sound, etc.).
*2
This value may vary depending on the system environment. For example, it may be affected by noise
generated from other equipment.
Note
The Automatic power-switching function is available only when the POWER switch is set to ON.
Note
Be sure to set the POWER switch to OFF before you set the AUTO STANDBY switch.
LOW:
The Automatic power-switching function activates at a certain level of input signal.
To enable the function, select this position.
HIGH:
If the Automatic power-switching function does not work well when the AUTO
STANDBY switch is set to LOW, select this position. If the function still does not
work, slightly raise the LFE LEVEL on the amplifier.
OFF:
The Automatic power-switchingy function may unexpectedly activate due to the
system environment, for example, if the subwoofer detects noise generated from the
peripheral components. In this case, select this position to disable the Automatic power-
switching function, and manually turn the unit on or off by using the POWER switch.
Notes
• The subwoofer uses a small amount of power in auto-standby mode.
• If you plan not to use the subwoofer for a long period of time, set the POWER switch on the
rear panel to OFF, or unplug the power cable from the AC outlet.
